Engine movement (deflection) is wasted horsepower, and that power is yours! BMR Suspension wants you to take it back with its polyurethane motor mounts for 2005 to 2017 Ford Mustang. BMR's new motor mounts (MM007) are far superior to the bulky, stock bushings, which are designed for comfort, not performance. BMR manufactures its MM007 polyurethane motor mounts in its Florida facility from CNC-laser cut ?-inch plate steel with aircraft-grade 7075 billet aluminum spacers and 95-durometer polyurethane bushings. The kit is completed with Grade-8 hardware. BMR Suspension designed the MM007 to be the perfect (100% bolt-in) motor mount for any power level or application (street performance, drag race, and road race) where engine deflection needs to be reduced. The factory motor mounts are designed to dampen engine vibration, giving you the smoothest and most comfortable experience possible. Unfortunately, this does little to limit engine movement. This deflection means lackluster throttle response, slower reaction times, and less accurate shifts in manual-equipped cars. BMR's MM007 polyurethane motor mounts limit engine deflection, while isolating much of the engine vibration from the vehicle's occupants. This means you won't feel a big increase in NVH. The reduction in deflection leads to less wasted power as it's transferred to the tires, improving your driving experience on both the street and track. And less drivetrain movement means more accurate shifts as you row through the gears. The MM007 weighs over 50-percent less than the factory engine mounts (8-pounds factory, 3.8-pounds MM007). They are also height adjustable. Simply remove the aluminum spacers to lower the engine a ?- or 1/2-inch in the engine bay (larger engine drops are possible?call for more info). This will give increased under-hood clearance for a strut tower brace or supercharger, and a lower center of gravity for improved handling. When performance is a must, rely on BMR Suspension!
